- Remove the ignore list and replace it with a quirk list of sorts.

- Add a quirk type for devices whose interrupt properties are actually
  attached to their children.
- Flag the "escc" (zs-alike serial controller) device as having this quirk.
- Rework the interrupt discovery code to deal with devices that have more than
  one interrupt.
